Perfect for my RV!

I just received my 100W Solar Panel Kit and it's fantastic! Setup was surprisingly easy with the included instructions. My RV's battery is staying fully charged now, even when we're off-grid for days. I was worried it wouldn't be enough power, but it totally delivers. I'm so glad I found POWOXI, I'll definitely be buying more accessories from them soon!

Works as expected

Got the Solar Car Battery Charger. It came fast. Easy to install. Keeps my car battery charged. No complaints.

Great deal on a solar maintainer

I was looking for a good price on a Solar Battery Maintainer for my ATV. I found the 12V Solar Battery Maintainer here and it was on sale, plus I got a newsletter signup offer which made it even cheaper. It arrived quickly and was easy to connect. It feels like I got a really good value for my money compared to other brands I checked. Very happy with this purchase, it's keeping my ATV battery healthy without breaking the bank.

Good charger, shipping was okay

I bought the 20W Solar Charger for my old boat battery. It works well to keep it topped off, even on partly cloudy days. The build quality feels solid for the price. My only minor issue was that shipping took 7 days to reach me in Florida, which felt a bit long. Customer service was helpful when I asked about tracking, though. Overall, a decent purchase for the value.

Can you actually leave these connected to your car battery while you're driving? Or do you have to disconnect it every time?

A Alex C. 1 week ago

No, you definitely need to disconnect it. It's not meant to be connected while the car is running.

B Brian 6 days ago

Most solar chargers aren't designed for that. The car's alternator takes over charging when it's on, and having the solar charger connected could potentially cause issues. Better safe than sorry, just unplug it.

Are these POWOXI chargers actually waterproof? I want to put it on my boat and don't want it crapping out after the first rain.

J Jeff Johnson 4 weeks ago

The marine ones are definitely waterproof, mine has been out in a few downpours and still works fine.

L Leah Wright 3 weeks ago

Some models are. You gotta check the specific product description for the one you're looking at. They usually list the IP rating if it's meant for weather.

Has anyone actually used their return policy? My luck with online stuff is usually terrible and I might need to send it back.

J James Thompson 1 week ago

yeah returns were easy, did it last month.

O Olivia T. 1 week ago

I had to return a faulty cable once. It was pretty straightforward, just follow the instructions on their site. Got my refund within a week or so after they received it.

I'm thinking about getting a solar panel for my RV, should I go with POWOXI or is Renogy better? What's the real difference?

Z Zach Parker 1 month ago

POWOXI is usually a bit cheaper and good for basic maintenance. Renogy is often more robust for full-on off-grid setups, depends on your needs.

B Brittany Roberts 1 month ago

For just keeping your RV battery topped off while parked, POWOXI is perfectly fine and more budget-friendly. If you're running a bunch of appliances, Renogy might be more powerful but also pricier.

Does anyone know if they do a first-time buyer discount? Trying to save a few bucks if I can.

W William Robinson 1 week ago

Pretty sure they do if you sign up for their newsletter. Check the popup when you first hit the site.

S Sam Martinez 1 week ago

Yeah, I got 10% off my first order for signing up. It was an automatic code in my email after I subscribed.

do their solar panels even work on cloudy days, or do you need full sun for them to do anything?

E Emma R. 2 weeks ago

They work, but much slower. Don't expect a full charge but it'll trickle.

R Robert Evans 2 weeks ago

Yeah, they'll still charge, just not as efficiently as a bright sunny day. Good enough to prevent your battery from dying, but if you need a quick charge, you'll want sun.

Any active coupon codes floating around right now for like, a sitewide discount?

S Susan Martin 1 month ago

Sometimes they pop up around holidays, check their main page banner.

E Elizabeth 4 weeks ago

Not sure about a general code right now, but I always get emails about specific product sales. Keep an eye on your inbox if you're subscribed.

Is POWOXI a legit brand or like, some random dropshipper stuff? Seen some iffy reviews for similar products elsewhere.

L Lisa Flores 1 month ago

They're legit. I've bought a few things from them, no issues.

A Amber G. 1 month ago

Totally legit. Been using their stuff for my ATV for over a year now and it's been solid. Good quality for the price, imo.
